Only properly trained personnel, who passed all applicable HV Technical Training Courses, should
perform repairs which require disconnecting, or removal of High Voltage battery
components on any
Hybrid
or Electric Vehicle. Work performed on High Voltage systems by unqualified persons may
result in severe injury or damage to the vehicle. Additional safety information is found in Repair

Prior to disconnecting, or the removal of any HV component, the HV system needs to be disabled
and secured (by means of the HV Disconnect Switch) by a properly trained technician, who has a
minimum HV Qualification level after completing the Technical Training Course ST1824 (Alternative
Drive Part 1). Once the vehicle’s HV system is disabled (the “Blitz” - lightning bolt icon displayed in
instrument cluster, see below), a technician without HV Certification may remove a HV component
(e.g., EH Heater, EKK Compressor, EME Control Unit, et.), except for the High Voltage Battery
.
High Voltage Battery
removal and rework can ONLY be performed by a High-voltage Certified
Technician with a HV Battery
Certification level corresponding to a specific Electric or Hybrid![]()
vehicle, for example:
To repair GEN4 HV battery
of G05 PHEV a certification from Technical Training Course “ST2006 –
SP44 HV Battery
” or equivalent ST1825 – Alternative Drive Part 2 is required (or as of 1/2023 the
equivalent “ST 2325 for High Voltage Battery
Systems”).
AndTo repair A GEN5 HV battery
the Technical Training Course “ST2205 Generation 5 High-voltage
class” is required or as of 1/2023* the equivalent “ST 2325 for High Voltage Battery
Systems”.
*Note: As of January 2023, the “ST2205 Generation 5 High-voltage stand-alone class” has been
merged into “ST2324 for High Voltage Drivetrain Systems” and “ST2325 for High Voltage Battery![]()
Systems”
The complete front electric drive unit is replaced; see repair instructions 12 35 521 “Replace front highlyintegrated electric drive topology completely (after vehicle diagnosis)”.
Important Note:
The replacement front electric drive unit comes pre-filled with fluid, eFluid transmission oil
PN 83 22 5A1D718.
Contrary to the repair instructions, there is no need for a wheel alignment and replacement of the
radial shaft seals. The repair instructions will be updated accordingly with the next release.
